Brief Summary

Preserved Ratio Impaired Spirometry (PRISm) describes individual with spirometry findings of forced expiratory volume (FEV1) and forced vital capacity (FVC) ratio greater than 0.7 but with the FEV1 less than 80% predicted. While the spirometry findings of individuals with PRISm can be transited into obstructive pattern, remains at PRISm or become normal spirometry, limited evidence is on the role of exercise in the course of PRISm. This study aims to investigate the role of exercise, namely exercise with telehealth and walking exercise, together with smoking cessation advice, would alter the clinical course of PRISm.

Outcome Measures

Primary Outcomes (1)

  • Change in 6 minute walk test distance

    The 6 minute walk test distance will be measured in the start of the study, at 3 months, 6 months and 12 months. The differences will be compared.
